Researchers develop 'breakthrough' in water testing
Drinking water can be tested for E. coli bacteria in three hours or less with simple, inexpensive paper strips developed by researchers at Waterloo Engineering.
Sushanta Mitra, a mechanical and mechatronics engineering professor, is working with colleagues at startup Glacierclean Technologies Inc. to refine the invention and hopes to have a product costing just 50 cents a test on the market within nine months.
